Retroperitoneal schwannomas

چکیده
BACKGROUND Retroperitoneal schwannomas are very rare and are usually found incidentally. CASES REPORT Two rare cases of retroperitoneal schwannomas are reported. Both were incidentally found during US scans for non-specific epigastric pain and were initially diagnosed as non-secreting retroperitoneal tumors. The diagnosis was confirmed by CT scan. In both patients the tumors were resected. The definitive diagnosis was possible by histopathology. CONCLUSIONS Although the preoperative assessment of a retroperitoneal tumor may be indicative of a retroperitoneal schwannoma, the definitive diagnosis is possible only by histopathology after surgical removal of the tumor.

متن کاملThe management of retroperitoneal giant schwannomas in AIDS patients: A case report
Retroperitoneal schwannomas are a rare disease. During the potent antiretroviral therapy era, the incidence of AIDS-defining cancers has decreased, while the incidence of non-AIDS defining cancers has increased; however, the existence of a relationship between benign or malignant schwannomas and AIDS remains unclear. Although a case of ethmoid malignant schwannoma in an AIDS patient was first r...
متن کاملA rare retroperitoneal schwannoma in a patient with neurofibromatosis Type 2
Neurofibromatosis Type 2 (NF2) is a dominantly inherited tumour-prone disorder, characterized by the development of multiple schwannomas, meningiomas and ependymomas. Its prevalence is around 1:60 000. Vestibular schwannoma (VS) is the hallmark of NF2. Retroperitoneal schwannomas are expected to occur in only 3% of cases. We present the case of a large retroperitoneal schwannoma in a patient wi...
